  • 摘要: 泰国横跨2个生物多样性热点地区,但是对许多现存的两栖动物的物种多样性仍然知之甚少。异角蟾属物种形态保守,主要生活在森林中。在泰国,该属拥有许多隐存物种。在此,我们收集了来自泰国北部清迈省的茵他侬山国家公园异角蟾属的个体,这些个体以前被鉴定为Xenophrys minor。分子和形态分析发现,这些个体明显不同于同属的其他物种,因此我们将其描述为一个新种。通过结合以下形态特征能够很好的将该新种与同属的其他物种区分开:鼓膜明显且圆形;犁骨棱不明显,犁骨齿缺乏;舌呈心形后端无缺刻;指和趾侧缘膜缺乏;雄性第一指有婚垫;内蹠突大,外蹠突缺乏;背部表面有一个完整的深褐色眶间三角形,中间有淡斑,有两个明显的反向的“V”形淡红色腺脊;雄性腹股沟呈橘红色,与周围区域形成鲜明对比;内掌突和外掌突呈微红色。该新种目前已知仅分布于模式产地。该新种的发现进一步丰富了该属的物种多样性,未来需要大量的调查研究来进一步揭示泰国异角蟾属的生物多样性。此外,我们的系统发育分析也表明X. latidactylaX. palpebralespinosa的同物异名。
